Use the commands summarized in Table 65 to view and manage port logs. See the Fabric OS Command
Reference for additional information about these commands.
The portLogDump command output (trace) is a powerful tool that is used to troubleshoot fabric issues.
The portLogDump output provides detailed information about the actions and communications within a
fabric. By understanding the processes that are taking place in the fabric, issues can be identified and
located.
The portLogDump command displays the port log, showing a portion of the Fibre Channel payload and
header (FC-PH). The header contains control and addressing information associated with the frame. The
payload contains the information being transported by the frame and is determined by the higher-level
service or FC_4 upper level protocol. There are many different payload formats based on the protocol.
